Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of prefabricated buildings, and particularly relates to a column module of a prefabricated building and a column construction method. BACKGROUND

[0002] The building column, as one of important structural components of a building project, needs to bear the weight of the building. The prefabricated building, as its name implies, is to assemble various prefabricated components of the building at the construction site to directly form the building. In the prefabricated construction process, the column is also in the form of a prefabricated part and is assembled on the prefabricated component of the building.

[0003] In the prior art, the column of the prefabricated building is formed by surrounding a mold with a formwork, and the formwork on the four sides of the column needs to be installed and fixed one by one in the use process. The column module is roughly divided into four parts, which correspond to the four faces of the column, respectively. Therefore, whether in the process of installing the column module or in the process of disassembling the module for transportation, a large number of scattered column modules will increase the difficulty of the work, resulting in slow production of the column prefabricated parts.

[0004] For example, Chinese Patent Application No. 201911066410.5 discloses a detachable prefabricated building mold, which comprises a left moving mechanism, a right moving mechanism, a front moving mechanism, a rear moving mechanism, a left splicing plate, a right splicing plate, a front splicing plate, a rear splicing plate and a bottom plate. The left moving mechanism comprises a left threaded rod, a first left connecting plate, a second left connecting plate, a first left horizontal rod, a second left horizontal rod and a left L-shaped plate. The right moving mechanism comprises a right threaded rod, a first right connecting plate, a second right connecting plate, a first right horizontal rod, a second right horizontal rod and a right L-shaped plate. The front moving mechanism comprises a front threaded rod, a first front connecting plate, a second front connecting plate, a first front horizontal rod, a second front horizontal rod and a front L-shaped plate. The rear moving mechanism comprises a rear threaded rod, a first rear connecting plate, a second rear connecting plate, a first rear horizontal rod, a second rear horizontal rod and a rear L-shaped plate. The left splicing plate, the right splicing plate, the front splicing plate and the rear splicing plate and the bottom plate can form a closed space by cooperation with each other, and the left splicing plate, the right splicing plate, the front splicing plate and the rear splicing plate can be disassembled and replaced. Different sizes of the bottom plate, the left splicing plate, the right splicing plate, the front splicing plate and the rear splicing plate cooperate with each other, so that different sizes of beams, columns, floors and shear walls can be manufactured. However, the assembly process is still relatively complex. SUMMARY

[0013] Further, the end of the connecting pipe is provided with a sealing ring corresponding thereto, the size of the sealing ring is matched with the connecting groove, and the four connecting pipes are connected in communication with the same negative pressure device through a pipeline

[0014] Further, the top and bottom of the template are provided with guide rails in the length direction thereof, and the two ends of the connecting frame are provided with sliding blocks corresponding thereto, and the connecting frame on each template is slidably assembled on the adjacent template through the sliding block.

[0015] Further, the template is rotationally installed between the sliding blocks at the two ends of the connecting frame at the end thereof.

[0016] Further, a supporting assembly is connected between the template and the connecting frame at the end thereof, and the supporting assembly is used to rotate the template relative to the adjacent template when the connecting frame slides along the adjacent template close to it.

[0017] Further, the supporting assembly comprises:

[0018] two first connecting rods, which are respectively installed between the outer end of the connecting seat and the top and bottom of the connecting frame; and

[0019] a second connecting rod, which is rotationally installed between the outer end of the connecting seat and the template corresponding to the connecting frame, and one end of the second connecting rod is horizontally slidably installed on the template corresponding to the connecting frame.

[0020] Further, a sliding groove is processed on the template and distributed in the horizontal direction, a sliding seat is slidably arranged in the sliding groove, and one end of the second connecting rod is rotationally installed on the sliding seat.

[0021] Furthermore, the support component is provided with a limiting component, which is used to limit the relative rotation between the templates after the column module is unfolded.

[0022] Furthermore, the limiting component includes a connecting shaft and a nut. The outer end of the connecting seat is provided with a second mounting seat. The other end of the second connecting rod is rotatably connected to the connecting seat through the connecting shaft. The upper end of the connecting shaft is threaded, and the nut is assembled on the outside of the thread.

[0023] Furthermore, the back of the connecting frame is provided with a sealing strip to seal the gap between the connecting frame and the template that slides with it; the two sides of the connecting frame are provided with sealing seats to seal the gap between the connecting frame and the template on which the connecting frame is located.

[0027] After demolding, the templates are folded and gathered by rotating between the template and the connecting frame and by sliding the connecting frame along the adjacent templates.

[0028] 3. Beneficial effects

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] (1) The present invention connects adjacent templates by setting up connecting components, and optimizes the structure of the connecting components. The connecting frame at one end of the template drives the template to slide on the adjacent template, and drives the template to rotate relative to the connecting frame at its end, so that it can rotate relative to its adjacent template. Therefore, it is convenient to directly fold and unfold the column module, which is beneficial to the transportation of the column module and the template assembly during column pouring, and greatly improves the construction efficiency.

[0031] (2) The present invention sets a connecting seat on the connecting frame and a connecting pipe on the template at the other end away from the connecting frame. The end of the connecting seat is machined with a connecting groove that matches the connecting pipe. This allows the adjacent templates to be connected after unfolding, thereby improving the installation and connection stability of the entire column module after unfolding. On the other hand, the gas in the four connecting pipes and connecting seats can be extracted simultaneously by the same negative pressure device, so that the four templates can slide relative to each other at the same time, which is conducive to further improving construction efficiency.

[0032] (3) The present invention provides a support component between the template and the connecting frame at its end, so that when the connecting frame slides along the adjacent template close to it, the template where the connecting frame is located rotates relative to the adjacent template, which is beneficial for unfolding and folding the column module; and the support component is also provided with a limiting component, so that after the column module is fully unfolded, it can limit the relative rotation between the templates, which is beneficial for improving the stability of the module during column casting.

[0041] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0042] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0043] It should be noted that in the description of this invention, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Similarly, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] One embodiment of the present invention provides a column module for prefabricated buildings, such as... Figure 1 As shown, the column module is composed of four templates 1 connected end to end, with adjacent templates slidably connected by connecting components. Combined with... Figure 3 , Figure 4 The connection component includes:

[0046] The connecting frame 3 is rotatably disposed at one end of each template 1 along the height direction, and can be slidably assembled on the adjacent template 1 close to it along the length direction. Therefore, the template 1 can be driven to slide along the length direction of its adjacent template 1 through the connecting frame 3.

[0047] The connecting seat 11 is vertically disposed on the outer side wall of the connecting frame 3 and parallel to the adjacent template 1, and the end of the connecting seat 11 is machined with a connecting groove 15 extending along its length direction.

[0048] The connecting pipe 13 is installed in the connecting groove 15, and the shape and size of the connecting pipe 13 match the connecting groove 15.

[0049] That is, each of the four templates 1 has a connecting frame 3 and a connecting seat 11 at one end, and a connecting pipe 13 at the other end. When assembling the column module, the connecting seat 11 on the template 1 corresponds to the connecting pipe 13 on its adjacent template. The connecting frame 3 drives the template to slide along its adjacent template, and the template where the connecting frame 3 is located rotates relative to the connecting frame, so that each template can be unfolded or folded. This facilitates the transportation of the column module and also facilitates direct unfolding on site, greatly improving the construction efficiency of the column and overcoming the shortcomings of the prior art that requires the four templates to be installed one by one. In this embodiment of the invention, one end of the template is provided with a fixing frame 12, and the connecting pipe 13 is installed on the fixing frame 12.

[0050] Meanwhile, this invention further improves the connection stability of the entire module by using the connecting pipe 13 and the connecting seat 11 on the template for coordinated operation. When each template 1 is slid open, the connecting seat 11 on the template connects to the connecting pipe 13 on the adjacent template. Furthermore, the end of the connecting pipe 13 is equipped with a sealing ring 14. When the sealing ring 14 on the connecting pipe 13 enters the connecting groove 15 of the connecting seat 11, the connecting pipe 13 is connected to the negative pressure device. When the negative pressure device is working, it extracts air from the connecting groove 15 through the connecting pipe 13 and seals the connecting groove 15 with the external environment through the sealing ring 14, reducing the air pressure inside the connecting groove 15. This causes the connecting seat 11 to move, which in turn moves the connecting frame 3, thereby moving the template 1 as well. Therefore, by connecting four connecting pipes 13 to the same negative pressure device, the synchronous movement of the four templates can be achieved, allowing the column module to unfold and the four templates 1 to enclose a casting mold for the column.

[0051] Specifically, in this embodiment of the invention, guide rails 8 are provided at the top and bottom of the template 1 along its length, and sliders 9 are provided at both ends of the connecting frame 3. Each template 1 is rotatably mounted between the upper and lower sliders 9, and the connecting frame 3 on the template 1 is slidably assembled onto the adjacent template 1 through the sliders 9. The cooperation of the guide rails and sliders facilitates the relative sliding of adjacent templates to realize the unfolding or folding of the module. However, it should be noted that other sliding connection structures can also be used.

[0052] As a further improvement of the present invention, a support component is connected between the template 1 and the connecting frame 3 at its end. The support component is used to enable the template 1 where the connecting frame 3 is located to rotate relative to the adjacent template 1 when the connecting frame 3 slides along the adjacent template 1 close to it, thereby realizing the unfolding and folding of each template.

[0053] Specifically, in combination Figure 1 and Figure 3 In one embodiment of the present invention, the support component includes:

[0054] Two first connecting rods 5 are respectively installed between the outer end of the connecting seat 11 and the top and bottom of the connecting frame 3. The top and bottom of the connecting frame 3 are each provided with a first mounting seat 4 rotatably connected to the first connecting rod 5; and

[0055] The second connecting rod 7 is rotatably mounted between the outer end of the connecting seat 11 and the template 1 where the corresponding connecting frame 3 is located, and one end of the second connecting rod 7 can be horizontally slidably mounted on the template 1 where the connecting frame 3 is located. Specifically, as shown... Figure 2 , Figure 5 As shown, the template 1 of this embodiment of the invention is processed with a horizontally distributed groove 2, a slide block 16 is slidably disposed in the groove 2, a second mounting seat 6 is provided at the outer end of the connecting seat 11, and the two ends of the second connecting rod 7 are rotatably connected to the slide block 16 and the second mounting seat 6 respectively.

[0056] As a further improvement to this embodiment of the invention, the support assembly is provided with a limiting component, which is used to limit the relative rotation between the templates 1 after the column modules are unfolded. Figure 5 In one embodiment of the present invention, the limiting component includes a connecting shaft 20 and a nut 17. The second connecting rod 7 is rotatably connected to the connecting seat 11 via the connecting shaft 20, and the upper end of the connecting shaft 20 is threaded with a thread 19. The nut 17 is fitted onto the outside of the thread 19, and a rubber gasket 18 is provided between the nut 17 and the thread 19. Specifically, the connecting shaft 20 is restricted to rotate by a tool, and then the nut 17 is driven to rotate. The nut 17 compresses the rubber gasket 18, causing the rubber gasket 18 to deform. This deformation, combined with the thread on the surface of the bolt 19, fixes the bolt 19, thereby restricting the rotation of the connecting shaft 20. Finally, the rotation of the second connecting rod 7 is restricted. The second mounting seat 6, the second connecting rod 7, and the slide 16 prevent the templates from rotating, thus achieving final fixation between adjacent templates.

[0057] During folding, the rotation of the support component allows the connecting frame 3 to continue moving when the connecting seat 11 cannot move. This movement then moves the template 1 to the end of its adjacent template, facilitating the folding process. When unfolded and the adjacent templates are perpendicular, the limiting component restricts the relative rotation between the second link 7 and the second connecting block 6. The second link 7 and the slide 16 then limit the angle between the two adjacent templates 1, thus preventing template displacement during demolding from hindering the casting process.

[0058] Combination Figure 6 In this embodiment of the invention, a sealing strip 10 is provided on the back of the connecting frame 3 to seal the gap between the connecting frame 3 and the template 1 that slides with it; sealing seats 22 (rubber seats) are provided on both sides of the connecting frame 3 to seal the gap between the connecting frame 3 and the template 1 where the connecting frame 3 is located.

[0059] Another embodiment of the present invention provides a method for constructing columns in prefabricated buildings. Utilizing the column modules in any of the above embodiments of the present invention, each connecting frame 3 drives its corresponding template 1 to slide along adjacent templates 1, causing relative rotation between adjacent templates 1, thereby unfolding the column module. After unfolding, the adjacent templates 1 are perpendicular to each other. Precast column components are then poured into the cavity formed by the column modules. After demolding, the templates 1 containing the connecting frame 3 are folded and retracted through rotation between the template 1 and the connecting frame 3, and through sliding of the connecting frame 3 along adjacent templates 1. The specific construction process is as follows:

[0060] During use, with the assistance of slider 9 and guide rail 8, the connecting frame 3 on template 1 can slide on the surface of its adjacent template 1 until the connecting groove 15 on the connecting seat 11 and the sealing ring 14 come into contact. When the sealing ring 14 on the connecting pipe 13 enters the connecting groove 15 of the connecting seat 11, the connecting pipe 13 is connected to the negative pressure device. When the negative pressure device is working, the air inside the connecting groove 15 is extracted through the connecting pipe 13, and the sealing ring 14 seals the connecting groove 15 and the external environment, thereby reducing the air pressure inside the connecting groove 15, causing the connecting seat 11 to move. During the movement of the connecting seat 11, the connecting frame 3 moves, which in turn causes the template 1 to move relative to its adjacent template, thus realizing the unfolding of the column module. The four templates 1 enclose the mold to form a column.

[0061] By connecting the four connecting pipes 13 through the same pipe and negative pressure equipment, each template can move the same distance. During the rotation of the template around the connecting frame 3, the second connecting rod 7 rotates around the second mounting seat 6 by sliding the slide block 16 along the slide groove 2. When all templates reach the appropriate position and the adjacent templates are perpendicular to each other, the templates can be completely enclosed to form a column mold. At this time, the rotation of the connecting shaft 20 is restricted by the tool, and then the nut 17 is driven to rotate. The nut 17 squeezes the rubber gasket 18, and the rubber gasket 18 deforms. It cooperates with the thread on the surface of the bolt 19 to fix the bolt 19, thereby restricting the rotation of the connecting shaft 20 and finally restricting the rotation of the second connecting rod 7. The second mounting seat 6, the second connecting rod 7 and the slide block 16 prevent the adjacent templates 1 from rotating, thus fixing the adjacent templates.

[0062] Finally, the gaps between the connecting frame 3 and each template are sealed by the sealing strip 10 and the rubber seat 22, and the casting of the column prefabrication can be carried out. After demolding, the adjacent templates can be folded and stored in a parallel state by the rotation between the connecting frame 3 and its template 1, and by the sliding of the connecting frame 3 on the surface of the adjacent template. The four column modules are stored in a unified manner by folding, which is convenient for unfolding and folding, avoids a lot of fixing work during use and the integrity during transportation, and improves the efficiency of column prefabrication production.
